Abstract

Purpose

This study was conducted to compare the diagnostic yields of Ultrasonography-guided core needle biopsy (USG-CNB) and open surgical biopsy (OSB) in head and neck (HN) lymphoma and to identify the factors that shape USG-CNB diagnostic yield.

Materials and methods

All consecutive patients who were diagnosed with HN lymphoma in our hospital were analyzed. The frequencies with which these first-line procedures yielded a sample that permitted histological confirmation of lymphoma were determined. To identify the factors that shape the diagnostic yield of USG-CNB, the patients in whom USG-CNB was and was not sufficiently confirmatory were compared in terms of demographics, computed tomography (CT) and pathological findings.

Results

In total, 83 patients underwent USG-CNB (n = 26, 31.3%) or OSB (n = 57, 68.7%) for confirming lymphoma. USG-CNB yielded a fully sufficient diagnosis in 18 (69.2%) patients. By contrast, OSB yielded a confirmative diagnosis in 56 (98.2%) patients. Maximal standardized uptake value (SUVmax) of targeted LN on positron emission tomography-CT (PET-CT) in confirmatively diagnosed subjects was much higher than deferred counterparts (22.9 ± 13.4 vs. 10.1 ± 5.2, p = 0.017), however, there was no significant difference in other parameters associated with the first-line USG-CNB diagnostic success.

Conclusions

First-line USG-CNB was less frequently successful than OSB for diagnosing HN lymphoma involving cervical LN. Mean SUVmax of LN on PET-CT in confirmatively diagnosed subjects was higher than deferred counterparts on USG-CNB.
